Solution: Exercises 1 to 3
1 Basic Coin Counting
Exercise 1
Count the following coins and write the total amount:
2 quarters, 3 dimes, 1 nickel, 4 pennies
Definition:

Coin Values: Penny = 1¢, Nickel = 5¢, Dime = 10¢, Quarter = 25¢

Worksheet Steps:

Count each type of coin separately, then add all amounts together

Step 1: Count quarters

2 quarters = 2 × 25¢ = 50¢

Step 2: Count dimes

3 dimes = 3 × 10¢ = 30¢

Step 3: Count nickel

1 nickel = 1 × 5¢ = 5¢

Step 4: Count pennies

4 pennies = 4 × 1¢ = 4¢

Step 5: Add all amounts

50¢ + 30¢ + 5¢ + 4¢ = 89¢

Answer Key:

Exercise 1: 2 quarters + 3 dimes + 1 nickel + 4 pennies = 89¢

Total: 89¢
Final answer:

2 quarters, 3 dimes, 1 nickel, 4 pennies = 89¢

Applied rules:

• Separate counting: Count each coin type individually

• Multiplication: Number of coins × value of each coin

• Addition: Add all calculated amounts together

2 Money Comparison
Exercise 2
Which is greater? 4 dimes OR 1 quarter + 2 nickels?
Definition:

Money Comparison: Calculate each group's total value and compare using >, <, or =

Left Side: 4 Dimes
10¢
10¢
10¢
10¢
40¢
Right Side: 1Q + 2N
25¢
5¢
5¢
35¢
Step 1: Calculate left side

4 dimes = 4 × 10¢ = 40¢

Step 2: Calculate right side

1 quarter = 1 × 25¢ = 25¢

2 nickels = 2 × 5¢ = 10¢

Total right = 25¢ + 10¢ = 35¢

Step 3: Compare the amounts

40¢ > 35¢

Step 4: Write the comparison

4 dimes > 1 quarter + 2 nickels

Answer Key:

Exercise 2: 4 dimes > 1 quarter + 2 nickels (40¢ > 35¢)

4 dimes > 1 quarter + 2 nickels
Final answer:

4 dimes is greater than 1 quarter + 2 nickels

Applied rules:

• Separate calculation: Find total for each group

• Comparison: Use >, <, or = symbols

• Verification: Double-check calculations

3 Word Problem
Exercise 3
Tom has 3 quarters and 2 dimes. He spends 65¢ on a snack. How much money does he have left?
Definition:

Word Problems: Real-life scenarios requiring mathematical operations

Solution Plan:

Step 1: Calculate total money
Step 2: Subtract amount spent
Step 3: Find remaining amount

Tom's Money
25¢
25¢
25¢
10¢
10¢
95¢
Amount Spent
- 65¢
= 30¢
Step 1: Calculate Tom's total money

3 quarters = 3 × 25¢ = 75¢

2 dimes = 2 × 10¢ = 20¢

Total money = 75¢ + 20¢ = 95¢

Step 2: Subtract the amount spent

Money left = 95¢ - 65¢ = 30¢

Step 3: Verify the calculation

Spent + Left = 65¢ + 30¢ = 95¢ ✓

Answer Key:

Exercise 3: Tom has 30¢ left after spending 65¢

Tom has 30¢ left
Final answer:

Tom has 30¢ left after buying the snack

Applied rules:

• Problem analysis: Identify what's given and what's asked

• Subtraction: Money left = Starting money - Amount spent

• Verification: Check that Amount spent + Remaining = Total

Solution: Exercises 4 to 5
4 Making Change
Exercise 4
You buy a book for 87¢. You pay with 4 quarters. How much change do you get?
Definition:

Making Change: The money returned when payment exceeds the purchase price

Payment: 4 Quarters
25¢
25¢
25¢
25¢
$1.00
Cost of Book
- 87¢
= 13¢
Step 1: Calculate total payment

4 quarters = 4 × 25¢ = 100¢ = $1.00

Step 2: Subtract the cost

Change = Payment - Cost

Change = $1.00 - 87¢ = $1.00 - $0.87 = $0.13 = 13¢

Step 3: Express change in coins

13¢ = 1 dime (10¢) + 3 pennies (3¢)

Step 4: Verify the calculation

Cost + Change = 87¢ + 13¢ = 100¢ = Payment ✓

Answer Key:

Exercise 4: Change = 13¢ (1 dime + 3 pennies)

Change: 13¢
Final answer:

You get 13¢ in change (1 dime and 3 pennies)

Applied rules:

• Subtraction: Change = Payment - Cost

• Coin combination: Express change using fewest coins possible

• Verification: Check that Cost + Change = Payment

5 Mixed Operations
Exercise 5
Sarah has 2 quarters, 4 dimes, and 3 nickels. She gives 50¢ to her friend. How much money does she have now?
Definition:

Mixed Operations: Problems involving multiple mathematical operations (addition and subtraction)

Solution Process:

Step 1: Calculate Sarah's initial money
Step 2: Subtract the amount given away
Step 3: Find the final amount

Initial Money

5¢
$1.05
Amount Given Away
- 50¢
= 55¢
Step 1: Calculate Sarah's initial money

2 quarters = 2 × 25¢ = 50¢

4 dimes = 4 × 10¢ = 40¢

3 nickels = 3 × 5¢ = 15¢

Initial total = 50¢ + 40¢ + 15¢ = 105¢ = $1.05

Step 2: Subtract the amount given away

Remaining money = $1.05 - 50¢ = $1.05 - $0.50 = $0.55

Step 3: Express in cents

$0.55 = 55¢

Step 4: Verify the calculation

Given + Remaining = 50¢ + 55¢ = 105¢ = Initial amount ✓

Answer Key:

Exercise 5: Sarah has 55¢ after giving 50¢ to her friend

Sarah has 55¢ now
Final answer:

Sarah has 55¢ after giving 50¢ to her friend

Applied rules:

• Multi-step problem solving: Break down into smaller parts

• Addition: Combine all initial amounts

• Subtraction: Remove the given amount

• Verification: Check that parts sum to whole
